Intracellular localization of LRV1 in infected Leishmania cells and epitope conservation of the coat protein.

Polyclonal antibodies were raised against a recombinant fragment of the coat protein of LRV1-1 to determine the epitope conservation of the coat protein among LRV1 isolates, and the intracellular localization of LRV1 particles in promastigote cells of Leishmania braziliensis. Western blot analysis showed that specific epitopes of the coat protein are highly conserved among isolates from different geographic areas. Using indirect immunofluorescence assays LRV1 viral particles were observed as fluorescent granules, limited to the cytoplasm and with no apparent association to the host organelles or the cell membrane, characteristic of a persistent, non-infectious virus.

[Leiomyosarcoma of the gastrointestinal tract].

The records and biopsies of 10 patients with the diagnosis of leiomyosarcomas admitted at the Military Hospital "Dr. Carlos Arvelo" from 1962 to 1991, were reviewed. The sample correspond to 0.47% of all gastro-intestinal tumors. Sixty per cent of tumors were localized in the stomach, 20% in the jejunum, 10% in the duodenum and 10% in the colon. Eighty per cent had pain and 60% had bleeding. Sixty per cent of tumors were low grade leiomyosarcomas and 40% were epithelioid leiomyosarcomas. In eight of nine patients operated, resection was done. The survival range was from six months to 28 years with a median of 12 years. The most important prognostic factor was the extension of the tumor, independently of he histologic type.

[Epidemiological study of pediculosis capitis and scabies in schoolchildren from Antofagasta, Chile, 1995].

In order to contribute to a better knowledge of the pediculosis capitis and scabies during March-December 1995, 1122 primary schoolchildren under 14 years of age in the city-port of Antofagasta in northern Chile (20 degrees South lat.), were examined. A total of 285 (25.4%) were found to be infested with Pediculus humanus capitis and only 20 (1.8%) with Sarcoptes scabiei. In general the rates of infestation to both ectoparasitic diseases were higher in groups of younger schoolchildren, also higher in women than in men and in those groups with high indexes of crowding and ignorance of the transmission mechanism of pediculosis capitis and scabies.
